Newbie question: sub-tasks?

I am a newbie to TD. I find the free version has lots of bells and whistles, which I am exploring, but probably don't need most of them. But still I am considering upgrading and have a question for those already using the Pro version.

How useful do you find the sub-task feature? Is it more trouble than it's worth? In other words, did any of you decide to sop using it ??

Any comments on pros and cons in general?

Apologies if this has been asked a zillion times before - any repllies would be much appreciated!

I can see the usefulness of sub-tasks for projects. Listing next actions only can be a bit frustrating - sometimes I really need to see further ahead! At the moment, I add further steps as notes to the next action, but then I have to copy them again and there is a risk they'll get deleted, so I am looking for a better way.

I can't imagine using Toodledo without the subtasks. I use parent tasks to track a multi-step project and then use subtasks to track the steps required to complete it.

There are several ways that you can mark steps that aren't needed yet so they don't clutter your working view (everyone seems to have their own approach), and any time you want to review the whole project, you can simply expand the parent task.

There's also now manual ordering of subtasks, so if some of your steps need to be completed in a specific order you can indicate that order in how they're listed. There's no way to emulate this in the non-pro account.
